Be it known that we, FRANK B. PARKER and HERBERT R. GooDFELLow, respectively a citizen of the United Statesandas'ubject of the' King of England, residing at Chicago, in the county of Cook and Statev of Illinois, have invented certain new and useful Im-k provements in Cleaners for WindshieldsfandY fthe like, of which the following Iis a speelication.

This invention relates to improvements in cleaners for wind shields and thev like pal",- ticularly adapted, though not necessaril J limited in its use withlmotor,` vehicles, an one of Lthe objects of the invention is to provide an improved device of this character adapted to traverse substantially the entire shield and which operation maybe contin lse nous or the'device may operate for any desired space of time according to the will of the operator.

A further object is to provide an improved mechanically operated device of this character having its operating' parts so are f construction,combination and arrangement of the several parts hereinafter more fully described and claimed and shown in the ac-4 companying drawing illustrating this in;I vention and in which- Figure 1 1s a view in elevation of the wind j shield of a motor vehicle having a cleaning device constructed in 'accordance with the principles of this inventionv applied thereto.' Figure 2isan1enlar`ged detail front elevation with parts broken away.

FigureB is a Isectional-view takeii on line "means of a motor 28 connected #with the Referring more particularly to xthe drawing the numeral designates wind shield of a motor-vehicle, -having the `usual frame 11. -4 u Arranged valong theupper edge; of the shield and to 'extend substantially-entirely across-theshieldr-is a shaft 12, which sfprogenerally the vided with a double screw 13,.- '.lhel shaft is mounted in suitable bearings carried in a y frame 14, the 'frame being of a substantially U shaped configuration forl housing -the 60 shaft, and the extren'iities ofthe frame are hanged as at and. by means of which flanges the framemay be secured in position preferably by fastening the same to the frame 11 of the windshield.

A traveling member 16 is mounted upon l the shaft l2. This member is provided with.`

an opening 17 ,into which a pin or lug 18 pro'- threads 13 of the shaft 12. The pin or lug 1s held in position in any suitable mannerv such asby means of a fastening screw 19, en-` tering the member 16 in such a position that the head of the screw will overlap the pin 18. When it is desired to remove the pin the screw may be first removed to permit the pinto be shifted so as to disengage the shaftv 12. A scraper" or wiper'20 is connected with .the member 16 in any suitable manner preferably by means of a link 21, whichis piv- V otally connected as at 22 with the wiper and is also'pivotally connected as at 23 with an arm like portion 24 ofthe member 16. A

spring, 25 is preferably arranged about the pivot 23 and operates upon the' arm 21, which latter 'is preferably in the yform of a link so Vas to move the arm in a direction to cause- "the wiper to Vbe normally held against the shield 10. f

AS a means for maintaininr the member 16 in theJ properv position and fir preventing the same from tilting downwardly away from the shield or screen,/any suitable means maybe lprovided but for that urpose the frame 141 may be employed. o that endthe walls 26 of the frame 14 terminate short of the frame 11 of the shield'or screen and connected with the member 16 arerollers 27, which are disposed between the ends of the walls 26 of the casing 14 and the frame 11 of the shield orvscreen,` thereby permitting the member 16 to travel'ralong the shaft 12 j The shaft is adapted to be rotated in any desired or suitableI manner preferably by shaft of which isa gear 29 preferably of ects and which pin or' lug engages in the y the beveled type, which'meshes with a gear s 30,`preferably ofthe beveled type, secured to the end of the shaft 12 so that when the motor is oy eratedthe shaft 12 will be roftated and' he direction of rotation of the shaft always remains constant. en the iro shaft is rotated the member 16 carrying with it the wiper 2() will be moved longitudinally of the shaft and across the screen or shield from one end thereof, covering substantially the entire area of the screen, until the member 16 reaches the limit of the screw which runs in one direction about the shaft 12. When the member 16 reaches the end of the shaft 12, the'screw threads or spirals which run in the Opposite direction V about the shaft-will receive the end'vof the pin 18 and the direction of movement of the member 16 will be reversed and the wiper will be caused to move across the ywind I shield in the opposite direction, the diree,

tion of travel of the member 16 being reversed as the member 16 reaches each end o f the shaft 12. I

Thus it will vbe manifest that the wiper 20 will be automatic in its action and will travel back and forth across the windshield or screen without interfering with the vision of the operator. The speed of travel of the Wiper is controlled by the speed of rotation of the shaft 12 and it is manifest that the gears 29-30 may be of any desired size and proportion to produce the desired rate of speed. The motor may also be of a size and speed to accomplish this result.

Any suitable means may be provided for controlling the operation of the motor and to that endthe motor may be driven from the battery, there being -provided a suitable switch device 31, in a convenient position for the operator. Obviously the motor 28 may be vsupported 1n any desired or suitable manner.

It w-ill also be manifest that this device may .be readily appliedto apwindl shield or screen and may as readily be removed, the

whole device being constructed as a unit.

While the preferred form of the invenltion has been herein shown and described it is to be understood that various changes may be made in the-details of construction' tamme of the shaft'. will cause thev said member to move therealong, a wiperpivotally connected with said traveling member, meansv tending normally to hold the wiper against the window, and rollers connected withthe said travelingmember onI oppositeV sides of the said shaft and movable 'across the adjacent face ofthe window or screen. 2. A cleaner of the character describe embodying a shaft extending ina direction across a window or screen, means for rotating' the shaft, a frame l1n whlch the shaft 1s dlsposed, said frame extendlng across the window or screen, a traveling member con-` nected with the shaft, means whereby the rotation of the shaft will cause vthe said member to move therealong, portions of the .said frame being spaced from the adjacent face of the window o r screen, ,rollers connected with the saidmember and disposedto engage the adj acent' portions of the frame and the face of the window or screen and 'to travel'in the space therebetween, a wiper pivotally connected with the said traveling member and movable across the window or screen, and means operating upon the wiper to hold :the same against the window.
